The Château de Tours was built in the 11th century. The building displayed an architecture of the Carolingian period, and was the residence of the Lords of France. Until the 2000s, the Royal Castle of Tours was used as an aquarium where about 1,500 fish of 200 different species could be seen. It also served as Grévin museum. The castle was classified as monument historique on 20 August 1913.
Currently, the building houses contemporary exhibitions of paintings and photographs, including works by Joan Miró, Daniel Buren,Nadar, and the workshop of Tours history where archaeological and historical documents, models, audio-visual films on the history of Tours, etc, are shown.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
